So I brought a set of E38 M pars to a reputable machine shop and had them bored to 74.1 mm. After finished I had them balanced and mounted and now feel a shake in the steering wheel between 40-50 mph. What Can I do to fix this this problem? Also what can I do if the hub is slightly off(too big)? I apologize a head of time is this question was already submitted in this forum..
